Method Detail

nextDoc

Advances to the next document in the set and returns the doc it is
currently on, or DocIdSetIterator.NO_MORE_DOCS if there are no more docs in the
set.NOTE: after the iterator has exhausted you should not call this
method, as it may result in unpredicted behavior.

advance

Advances to the first beyond (see NOTE below) the current whose document
number is greater than or equal to target. Returns the current
document number or DocIdSetIterator.NO_MORE_DOCS if there are no more docs in the
set.

NOTE: this method may be called with DocIdSetIterator.NO_MORE_DOCS for
efficiency by some Scorers. If your implementation cannot efficiently
determine that it should exhaust, it is recommended that you check for that
value in each call to this method.

NOTE: after the iterator has exhausted you should not call this
method, as it may result in unpredicted behavior.
